Study: Pfizer Covid-19 Vaccine Provides Less Immunity to Omicron Variant than Other Variants


According to a study, the covid-19 vaccine developed by Pfizer and BioNTech against the novel corona virus disease has actually been providing less immunity to the newly identified Omicron Covid-19 variant than the other variants of the corona virus variants.

In the experiments conducted in the lab that has been conducted at the Africa Health Research Institute in Durban, and it has also been observed that, the Omicron covid-19 variant that has been resulted in around a 40-fold decrease in the levels of the neutralization antibodies that had been produced by the people, who had received both the doses of the vaccine shot of Pfizer and BioNTech as compared to the other covid-19 strains.

Alex Sigal, who is the head of the lab research said, the loss of the protection of the immune system of the people has been robust but it is not complete, and the further studies regarding the efficacy are going to be needed for appropriately take on the board the exact extent of the impact of the covid-19 vaccines in the process of mitigating the disease that has been caused by the new Omicron variant of the virus.

Alex Sigal also said, there is going to be more breakthrough of the immunity induced by the corona virus vaccine as he has been pushing the idea of getting the corona virus booster shots for the purpose of protecting themselves against the new Omicron covid-19 variant.

He also said, a good covid-19 booster vaccine booster can possibly decrease the chance of getting infected by the new variants, especially the infection leading to severe diseases.
